Transportation Worker Identification Credential (TWIC)
Maritime workers including terminal employees, longshoremen, truck drivers, agents and contractors must have a TWIC to gain unescorted access to Maryland Port Administration (MPA) facilities.
TWIC is federally mandated and enforcement is carried out by the U.S. Coast Guard. More Information regarding TWIC can be found on the Coast Guard's web site at http://homeport.uscg.mil/twic or the Transportation Security Administration's (TSA) web site at https://www.tsa.gov/for-industry/twic . TWIC Enrollment Center locations and hours of operation can be found on TSA's website.
Although the MPA is not responsible for issuing the TWIC, there are some questions specific to the MPA facilities that are addressed here.
